In any ingredient list, the higher up (closer to the beginning) an ingredient is, the more of it there is in the product in question. According to this site, after "carbonated water" (the #1 ingredient) is glucose (pure sugar, in other words); after that is citric acid (vitamin C, basically), followed by sucrose (another form of sugar). Two of the top four ingredients are sugar, in other words. If you go down to the nutritional info, it also says that in an 8 oz serving there are 26 grams of sugar. And mind you, further down it says that there are two servings in the container, so if you down the whole can you really have to double that (52 grams of sugar!). There's a lot of vitamin C too, sure, but you can always opt for orange juice if that's what you're after, rather than going for vitamin C mixed with tons of sugar and then carbonated.

Really hate those drinks, they hand them out a lot on my campus tho. More than the sugar, I admit to a rampant sweet tooth that seems to not know when too much sweet is exactly "too much sweet", it's the horrible throat burning sensation you get when drinking them that bothers me.

Oh they creep me right out. I see school age kids with them all the time - I'm talking kids between 11-14 - and I just can't believe they are drinking this stuff. it's bad enough that adults and older teens/college kids drink them, but wow. I can't imagine just how bad they are.
